[Editor's note: Avenza's Photoshop raster mapping solution 2.5 update will allow ECW, MrSID and DEMs to be directly importable into Photoshop. Also new, crop before import to reduce file size and reproject on import to match an existing dataset.]
Avenza has announced an update to Geographic Imager, a Photoshop extension which handles geospatial content from sources such as satellites. Images can be imported, edited and exported using Photoshop, with special options for tasks like automatically tiling images, or geo-referencing them with ground control points. Version 2.5 adds support for DEM formats including USGS/CDED ASCII, and a collection of other standards including ECW, JPEG 2000 and military elevation data.
New features include the ability to crop on import, and thus trim down raster images which are otherwise too unwieldy. Automatic coordinate system transformation can now be performed during mosaic creation; this adjusts images with different coordinate systems and pixel sizes, conforming them to the intended output.
The update should be available in the third quarter of the year, either as a free release for those with maintenance subscriptions, or a $319 upgrade for those without. New licenses start at $699. The extension requires Photoshop CS3 or CS4, as well as 300MB of hard drive space.
